Rear Phil FSC Freehub - Clunk... Clunk... Clunk!
Phil Gurus,
I have one of these hubs on my regular road bike. This hub currently has about 13K miles on it. It has been ridden under fairly benign conditions and rarely in the rain. Last fall it developed pawl engagement clunk... clunk... clunk noises. Phil was nice enough to provide a new freehub body under warranty. This got rid of the noise for about 1500 miles. The noise has recently returned so I disassembled the wheel and cleaned and re-greased the assembly. While apart and clean I could readily see areas on the ratchet teeth where the pawls had been slipping i.e failing to engage the ratchet ring. On a ride today the noise was still there. At this point I am assuming that the ratchet ring needs to be replaced. Does anyone know if this can be done by a mechanically inclined individual or an experienced LBS? I am assuming that it might require special tools? This is my first experience with Phil hubs and I am really disappointed concerning their reputation for quality products. Is this the kind of mileage that I can expect from one of these hubs? Is this freehub design just finicky? i.e. if the moon, stars, and special grease viscosity all line up then they work properly. If not they begin eating themselves up in short order? I have noticed that even fully greased the pawls seem kind of "jerky" (not smooth) when pressed by a finger. I wonder if this is the same thing that is keeping them from fully engaging while in the hub. Should a special kind of grease be used on these? Thanks for any insight. Steve |

An uncommon situation with that hub. Not being able to see it, my thoughts are that your lubricant is too thick. A very thin grease maybe, but we prefer a gear oil on pawls. You should consult with your local Phil dealer or call Phil Wood. -- Andrew Muzi www.yellowjersey.org/ Open every day since 1 April, 1971 |

You should consult with your local Phil dealer or call Phil Wood. I had trouble with pawls not engaging properly using heavy gear oil (80w-140) in a Mavic hub. After the pawls slipped a few times the edge had worn off them and I reshaped them carefully with a file. Now I use much lighter oil (ATF), and have no problems. JS. |

Steve A common issue with these hubs (sorry Andrew, I saw a lot of these). If I recall correctly Phil recommends their own gear oil (repackaged gear oil with a fancy name) instead of grease. The circular spring can also be damaged/defective and then won't lift the pawls. |

I've had great luck with Phil's tenacious in freehubs. Stays put and makes them purr. Grease and pawls is generally a dumb idea. |

Even after they get a little dirt in them and start making a little noise I take then apart, clean everything up, re-lube and it is good to go for another 5K miles. Here it appears that once these hubs slip once it is a down hill slide with no chance of recovery. Steve |

Steve A common issue with these hubs (sorry Andrew, I saw a lot of these). Interesting... I heard from Peter White today that Phil had a problem with these at one time with incorrectly machined parts. Is this what you are referring to or is this an ongoing issue? I am wondering if I got "lucky" enough to get one of these suspect hubs. If I recall correctly Phil recommends their own gear oil (repackaged gear oil with a fancy name) instead of grease. Not according to their current web site. They currently recommend that Phil grease be used. The amount depends on whether you go by what they tell you on the phone (a lot) or what is on the video on their Web site (a little). The only differnce that I have noticed is that the more grease you use the quieter the freewheel ratchet. The circular spring can also be damaged/defective and then won't lift the pawls. When I first talked to Phil about this issue that was their first thought and sent me a replacement spring. I replaced the spring which made no difference. |

The amount depends on whether you go by what they tell you on the phone (a lot) or what is on the video on their Web site (a little). The only differnce that I have noticed is that the more grease you use the quieter the freewheel ratchet. I think that they tend to pack them pretty full to lower the ratchet noise. I have been using Amzoil 100% synthetic multipurpose grease which is a thin grease and appears to be about the same viscosity as the Phil grease. I have used this for years in other hubs and freehub assemblies without a problem. I can sort of see an argument against oil in that it will flow a lot more readily than grease and will eventually run off the surfaces to be lubricated resulting in a lack of lubrication. The grease tends to stay put solving this issue. However, the thickness of the grease may result in other issues as Andrew has noted by not allowing the pawls to move fast enough or fully engage. BTW, I can't imagine how LOUD the ratcheting of one of these hubs would be with just gear oil lubrication. It was already pretty loud with grease. Steve |

The grease tends to stay put solving this issue. Oil runs off and runs back on again, providing actual lubrication. Grease by itself is not a lubricant. It gets pushed aside and acts only as a sponge for oil which is the real lubricant. Grease used for bearing lubrication is actually a mixture of grease (the sponge) and oil (the lube). The lubricant must be able to flow. Grease alone does not do this. However, the thickness of the grease may result in other issues as Andrew has noted by not allowing the pawls to move fast enough or fully engage. Precisely. JS. |

Send it back to Phil or Peter or someone and get it fixed. I used to take things back to Phil anytime a bearing blew or BB broke, but again, that was back when Phil was Phil-the-man, and I Iived down the street from the shop and would just walk in and get service. I never had to ship a wheel or look for service in a far away locale.-- Jay Beattie. |
